Application industries

Where our busbar processing machines are used

Low and medium voltage switchgear

Building low and medium voltage switchgear requires repeatable holes, slots and bends on copper busbars. Our CNC punching and bending machines hold constant tolerances across serial batches, removing manual correction and the copper scrap typical of bench work.

Busbars up to 15×200 mm and 16×200 mm
Positioning 0.10 mm over 500 mm
Automatic cycles with no repositioning

Transformers and prefabricated substations

In transformers and prefabricated substations, connection busbars need flat contact surfaces and low-resistance joints. The CNCMN-200A CNC busbar chamfering and milling centre prepares bar ends with ±0.08 mm accuracy.

Bar lengths from 150 to 6000 mm
Thicknesses from 4 to 16 mm
Repeatable chamfers for bolted joints

Power distribution and busway systems

Busway systems need long, accurate, continuous punching on bars up to 6 metres. Our 8-station punching machines with automatic feeding finish complete batches without tool changes, using dedicated loading and unloading stations.

Bars up to 6000×200×15 mm
Linear turret with 8 die stations
Loading station 3000 mm, unloading 2500 mm

Frequently asked questions

Answers to the questions we hear most from panel builders

How long do installation and operator training take?

Standard commissioning takes 1 to 3 working days and covers mechanical installation, hydraulic and electrical connection, acceptance testing and operator training. For 3-in-1 combined machines the acceptance test is run on sample busbars supplied by the customer.

Are the machines CE certified?

All LT machines are supplied with CE marking, a declaration of conformity and English or Italian manuals. The company is ISO certified and holds technical and design patents.

What accuracy is guaranteed when processing copper busbars?

Positioning accuracy is 0.10 mm over 500 mm on the X and Y axes, with punching accuracy of ±0.2 mm. On CNC bending machines positioning accuracy is ±0.15 mm and bending angle accuracy is ±0.3 degrees.

Do you supply spare parts and technical support for Europe?

The spare parts stock covers punches, dies, milling cutters and proximity sensors, shipped within 48 hours. Remote technical support is free and covers diagnostics, working parameters and operator training.

What busbar thickness and width can the machine handle?

The range covers busbars from 4 to 16 mm thick and 30 to 200 mm wide, up to 6000 mm long. HQ600 models reach 15×200 mm and the 503U-3-C series reaches 16×200 mm.

What are the delivery times?

Standard models are available in 15 to 25 working days. Sea freight to European ports takes approximately 30 to 35 days, with wooden case packing and complete customs documentation.
